Application March 13, 1945, Serial No. 582,447

2 Claims. 1

This invention relates to a holding frame for core strips and particularly the core strips employed in processing plywood and primarily it is an object of the invention to provide a frame for effectively holding the core strips in a manner whereby the layers of veneer can be glued on opposite sides thereof. Furthermore, it is an object of the invention to provide a frame of this kind comprising a plurality of separate members and wherein certain of said members are provided with means for coaction with the remainder for maintaining the core strips in proper relation.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved holding frame for core strips whereby certain important advantages are attained and the article rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view in elevation showing a frame constructed in accordance with an embodiment of the invention in working application with respect to the core strips, with portions broken away;

Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1, with veneer layers applied to the core strips;

Figure 3 is a View in an end elevation of one of the holding members of the frame.

In the embodiment of the invention as illustrated in the accompanying drawings, the frame comprises two elongated side members I of desired length and two end or holding members 2 of preferred length. The members I along their inner faces are provided at spaced points with the outstanding penetrating members or spuds 3. and the members 2 at opposite ends thereof is each provided with the holding brackets 4 and 5. Both of these brackets 4 and 5 are of channel formation and substantially right angular in form. These brackets 4 and 5 have arms a, and b respectively which straddle the end portions of a member 2 and are riveted, as at 6, or otherwise rigidly secured to the member 2. The second arms and d of the members 4 and respectively are disposed laterally and to one side of the member 2 and when the frame is in working assembly, these arms 0 and d straddle end portions of the members I.

The intermediate portion of the arm 0 of each bracket 4 is cut away at the outer extremity of the arm 0 and extending outwardly from said arm 2 c at opposite sides of said cut out portion are the lugs I between which is rotatably supported by the pin 8, an eccentric clamping disk 9 provided with an operating handle I0.

In practice the core strips S are positioned between the members I whereupon the end or holding members 2 are operatively engaged with the extremities of the members I. The handles Iii of the disks 9 are then swung in a direction to force the members I toward the ends of the core strips S resulting in the members or spuds 3 pressing into the ends of the strips S together with close contact with such ends. By this adjustment of the members I the strips S are effectively held in desired assembly to allow the veneer layers to be glued to opposite sides of the strips S in the usual manner afterwhich the frame is removed. The removal of the frame can be readily-effected by proper manipulation of the eccentric disks 9.

It is also to be stated that the brackets 4 and 5 can be employed merely as a retainer to hold the members I in place until the face veneers are glued on.

From the foregoing description it is believed to be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the-precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:

1. A frame for securing assembled core strips for plywood members, comprising a pair of spaced parallel bars, an arm secured to each end of each bar and extending at right angles therefrom toward an arm on the other bar, a second pair of spaced parallel bars disposed at right angles to and overlapping the ends of the first bars each bar of the second pair being engaged at each end against the inner side of an arm, and a force applying eccentric wheel rotatably supported upon one arm of each of the first bars and adapted when turned in one direction to engage its peripheral face against and apply thrust to the adjacent one of the other pair of bars whereby to effect the tight drawing of the ends of the bars of the first pair against the sides of the overlapping portions of the adjacent bars of the second pair.

2. A frame for securing assembled core strips for plywood members, comprising a pair of spaced parallel bars, a pair of angle members carried by each bar, each angle member comprising two right angularly related arms, one arm of each angle member having an end of a bar secured against the inner face thereof whereby the other arm of each angle member extends at right angles to the adjacent end of the bar to which it is 3 attached, a second pair of spaced parallel bars disposed perpendicular to and overlapping the ends of the first mentioned bars, each of the bars of the secondmentionedpair haying an end portion disposed :against.the innerlsideiof the other' arm of an angle member whereby each of said angle members encloses a corner of the frame formed by the overlapping ends of two bars, the said right angularly extending arm of one angle 1 H 10 member of each pair having an opening formed therein and having a pair of spaced parallel lugs extending outwardly therefrom, and an eccentric member pivotally mounted between each pair of lugs and adapted to extend through the opening of the adjacent arm for engagement against the outer side of the adjacent her, said eccentrics when turned in one direction functioning to draw the ends of the first bars against the overlapping MELVIN W.
